U Off Trips

U Off Trips is the Singleback set that turns 12 personnel into a run-heavy trips look. The U tight end is aligned off the ball as a wing on the trips side, the Y is attached, and a receiver sits outside them. The X is left alone on the backside. Standard Singleback sets spread the tight ends or stack them in-line. This alignment puts extra blocking mass to one side while keeping the U free to motion, arc, or cross the formation at the snap. Defenses usually respond by rotating a safety or walking a linebacker toward the trips side. That opens clean read keys for both the run game and play action.

The menu is built around gap and zone runs that use the U as a moving blocker. Inside Zone Split sends the U back across the formation to kick out or seal the backside end. HB Counter Str and Motion Power pull blockers to create numbers at the point of attack. Mtn Zone Toss and HB Misdirection punish defenses that overplay the strength. With a Power HB or 3DRB in the backfield, the formation has the same pre-snap picture on every play, which lets the ground game dictate the defensive structure.

The pass game comes off those run looks. PA Boot Slide and PA Dagger U Cross copy the Split action, with the U sliding into the flat or crossing underneath as the defense chases the run fit. PA Flood gives you a three-level stretch to the trips side. Mtn PA Y Corner isolates the Y against a linebacker or safety who has been triggering downhill. Because two tight ends are on the field, the defense often stays in base personnel. That hands you favorable size mismatches with the U and Y and a one-on-one shot for the backside X.
